Bug #3118

Updated by jeremyevans0 (Jeremy Evans) 11 months ago

=begin 
  
  Spent some time tracking down a segfault introduced in newer versions of 1.8.6.  
 
  mkent@el-test:~/git/matzruby (p306)$ ruby -v ~/open4_segfault.rb 
  ruby 1.8.6 (2010-02-05 patchlevel 399) [x86_64-linux] 
  1000 calls 
  /home/mkent/.gem/ruby/1.8/gems/open4-1.0.1/lib/open4.rb:52: [BUG] Segmentation fault 
  ruby 1.8.6 (2010-02-05) [x86_64-linux] 
 
  Aborted 
 
  After much testing it seems the changes introduced in 1.8.6 p306 are at fault as p305 and earlier don't exhibit the problem.  
 
  As 1.8.7 p174 and up work fine I've identified the following changes that correct the issue: 
 
  http://redmine.ruby-lang.org/repositories/revision/ruby-18?rev=25230 
  http://redmine.ruby-lang.org/repositories/revision/ruby-18?rev=25995 
  also requires 
  http://redmine.ruby-lang.org/repositories/revision/ruby-18?rev=16015 
 
  after which the example I've enclosed can do 200,000 calls without issue. 
 
 =end
